Radians Resistor™ 32 UF foam ear plugs feature a standard bullet/tapered shape to fit most adults, high visibility color, and a low pressure design that offers a comfortable fit for all day or all night wear. Some of the stiffer UF foam ear plugs available, Radians Resistors are still soft and smooth enough to provide very comfortable hearing protection, while also being a little easier to insert correctly for a proper fit.
